CAN DY-MACHINE.

SPECIFICATION forming part of Letters Patent No. 583,035, dated May 25, 1897.

Application filed August 8, 1895.

T0 otZZ whom it may concern:

Be it known that I, JOSEPH M. DEMERATH, a citizen of the United States, and a resident of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Candy-Machine, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a top plan view of one of my machines. Fig. 2 is a longitudinal section of the driving-pulleys and their connections. Figs. 3 and l are side elevations of the dipping devices, parts being removed in Fig. 4E to exhibit construction. Fig. 5 is afront elevation of a portion of the dipping devices. Fig. 6 is a bottom view of the tank, showing the operating mechanism for the stirring devices; and Fig. '7 is a cross-section of one of the stirring-paddles.

The object of my invention is to produce a machine for coating candies in quantity with any suitable coating material, such as chocolate; and my invention consists in the devices and combinations hereinafter described and claimed.

In the figures, A is a suitable framework or stand to support the mechanism.

A A and B B are respectively fast and loose pulleys for the driving-belts C D. The pulley A is fast upon a shaft E, while the pulleys A and B are loose thereon. The pulley B is fast upon one end of a sleeve E, which bears a worm E and at the other end apulley B Shifters a b are provided, which move the belts O and D, respectively, from the fast pulleys A and B to the loose pulleys A and B, and vice versa. A worm-wheel F on a transverseshaft F, supported in suit.- able bearings ff, meshes with the worm E On the shaft F is a cam G, substantially of the form shown in Figs. 3 and 4, having the deep notch g, the elevated portion 9 of the rim, and the lower portion g of said rim. A yoke H surrounds the shaft F by the long slot h, and at the end of the yokeis the stud H, which bears against the rim of the cam G, and the stud is moved by the revolution of the cam to operate the shank H of the yoke. The yoke is held in place on the shaft F by the collar h, Fig. 1. A bracket J, supported on the frame A", supports a lever K, pivoted Serial No. 558,692. (No model.)

to the bracket at k and to the end of the shank H of the yokeat As the cam G revolves it will cause the lever K to oscillate and to take difierent positions, according as the stud H rests in the notch g or against the portions g or g of the rim of the cam.

Upon the frame A rests a tank L for the coating material having a double bottom L for the introduction of steam or hot water by means of the inlet and drain pipes L (See Figs. 1 and 3.) The tank has a stirring device attached to it for mixing and stirring the coating material in order that it may be kept at a uniform consistency. Vertically through the bottom of the tank and in diagonal corners thereof are two rock-shafts Z. To the lower end of these shafts are attached links Z,which are connected together by the link Z (see Figs. 4 and 6,) and one of said links Z is also attached to a pitman P, which is connected to a crank l, which is driven by a beveled gear-wheel 1", which last is supported by a bracketl underneath the tank. The gear Z is driven by a beveled gear 13 on the end of the shaft E. (See Fig. 2.) The shaft E is supported at its end by the bracket and bearing 6. (See Fig. 4:.)

Inside the tank and upon each shaft Z is a stirrer U, which, as shown in Fig. 7, has a lower blade L, triangular in cross-section and with a base parallel and close to the bottom of the tank, and an upper blade U, which is in cross-section, a truncated triangle having its base at an angle of about sixty degrees to the base of the tank, a side parallel to said base side, and two other sides, one of which is at right angles to the base of the tank and the other of which is .at an angle of about thirty degrees to said base.

The operation of the gears beneath the tank driven by the shaft E causes the stirrer to vibrate between the positions shown in dotted lines in Fig. 6, and whichever may be the direction of motion of the stirrer the coating material is forced upward by the blade L from the bottom of the tank. When the movement of the stirrer is in one direction, the coating material is forced downward by the blade L from the top of the mass of the coating material, which should be substantially at the dotted lines in Fig. 7, and when the stirrer moves in the other direction the coating material is moved upward by the by means of the collar N, which is adjustable blade L from the center of the mass to the top. These currents of coating material will thoroughly mix the whole mass and will keep the same at a uniform consistency. The blades L" and L are fastened together by u prights L, Fig. 4, at the ends of the stirrer in a manner which is so obvious as to need no further description.

The bracket J bears the dipping apparatus, which I now describe. Upon the end of the bracket is a vertical guideway M, in which reciprocatcs a slide N, which bears a slotted bracket N. A pin 7.? connects the lever K with the bracket, so that as the lever K oscillates the slide N will move up and down in the guidcways M. Stops n a, one fixed to the guideway and the other to the slide, serve to limit the motion of the slide by means of the stem 12*, adjustable in one or the other of said stops. Supported by the slide N is a supportingframc O for the dipping device. This has the supportingarms pending therefrom, having their lower ends fastened to supporting-bars 0, which extend longitudinally from one end of the dipping device to the other. Upon these supporting-bars o rests the iudependentand insertabledippingframe P, which is arranged to support and retain the candies while being coated in the tank, and may be of any suitable form. The coating material in the tank is usually very thick and viscous, and consequently is apt to move the frame F, when the same is dipped into the coating material, unless the frame is properly held down. For this purpose I pro vide a clamping-frame. composed of the lougitudinal bars Q, which are fastened to end supports Q, and these end supports reciprocate vertically in guides attached to the frame O. The lever q operates links g, which. are pivoted to and straighten a pair of togglelinks if, attached to the ends of the supporting-bars Q, so that when the lever is in the position shown in Fig. 3 the clamping-bars Q, are raised from the frame P, and when the lever is thrown from the position just described to its extreme other position the links (12, being toggles, straighten and force the frame Q down upon the frame I and hold it securely in position. A spring-bar is provided with a lug which catches the handle q and holds it firmly in the clamping position.

Extending upward from the bracket J is another bracket R, which at its upper end has a bearing eontaininga shaft S, bearing a pulley S, which is situated immediately above the pulley 13 so that a belt may be run from one to the other, as shown in Fig. l, the belt, however, being omitted in order that the parts may be more clearly seen. ()u the opposite end of the shaft S from the pulley S is a wheel S having a series of corrugations upon its periphery. The slide F contains a central shaft 1P, which is connected to the frame 0. This shaft is supported upon the slide N on the shaft N and a spring N. (Shown in dotted linesin Fig. The springis supported at its lowerend upona fixed bcaringin the slide N, so that the shaft N may be pressed downward to compress the spring N" and may thus move the shaft longitudinally inside the slide N. The upper end of the shaft N is rounded, as shown in Fig. Ifnow the slide N is raised to its highest point, the end N of the shaft N" presses against the wheel S and if the wheel 8* is rotated, the slide N being held firmly by the cam G in the position shown in Fig. 3, the shaft N is reciproeated by each corrugation of the wheel S against the force of the spring N, and the result will be a rapid vertical shaking of the frame 0 and the candyframe 1 supported thereby. The purpose of the shaker is to remove with the utmost rapidity the surplus coating material as soon as the candy-support 1 has been elevated out of the coating-tank L.

The operation of my device is as follows: A suitable number of candies are placed upon the frame 1, which is slid into the machine upon the supporting-bars o. The handle (1 is turned to its clamping position and the frame Q clamps the frame P in position. If the coating material in the tank L needs stirring, the belt C is shifted by the pulley A and the shaft IE is thereby rotated, turning the gearwheels 13 and and oscillating the stirrers l. through the coating material until it is thoroughly mixed,whereupon the beltis shifted to the loose pulley A. The belt .D is now shifted from the loose pulley 1 to the tight pulley 13 upon the sleeve E. This revolves the worm E and the worm-wheel F, shaft F and cam G. At starting the parts may be in the position of Fig. 3 for illustrating their action. The cam G revolves in the direction shown by the arrow. \Vhile the pin ll" is upon the more elevated portion of the rim of the cam the corrugated wheel S operates the shaker, but when the pin 11 is on the less elevated portion of the rim of the cam the slide N is lowered and the wheel S does not operate upon the end N". As soon, however, as the pin II drops into the notch G the weight of the slide N and of the parts connected thereto oscillates the lever K and lifts the shaft ll of the yoke II and the dipping device will descend into the tank L and the frame 1 is immersed in the coating material. As the cam revolves further the pin II is depressed by the approaching side of the notch g and oscillates the lever K rapidly to its extreme limit of 1notion,'the pin ll. resting on the more elevated portion of the rim of the cam g and immediately brings the end N in contact with the wheel Thereupon the frame P is rapidly shaken and the surplus coating material is so jarred that it will drop back from the candies into the tank L. As the cam progresses in its movement, the pin II again meets the less elevated portion g of the rim of the cam. The end N parts may then be stopped for the removal of the tray P and for the insertion of another tray provided with its candies, whereupon the operation may be repeated. In order that the period of shaking may be increased or diminished, I provide a series of plates g which are clamped upon the rim of the cam in order to increase the diameter thereof and hold the pin H down for variable periods, according to the time deemed necessary to shake off the surplus coating material from the candies carried by the frame P. These plat-es are bolted to the rim of the cam in any suitable manner. The dotted lines in Figs. 3 and 4: indicate the bolts passing through said plates.
